Garrett Jones hit a one-out double off Papelbon, but Neil Walker flied out to right and Papelbon struck out Alvarez looking to end it. Papelbon is 55 for 55 in April save chances during his career.

Alvarez gave the Pirates a 1-0 lead when he drove his third homer out to right in the second. Martin led off the fifth with a drive to left to tie it at 2.

Pettibone helped Philadelphia get its first run when he walked in his first plate appearance in the third, advanced to second on Rollins' single, went to third on a grounder and scored on a wild pitch.

The Phillies briefly took a 2-1 lead in the fourth. Michael Young led off with an infield single, extending his hitting streak to 13 games. Domonic Brown walked and Ben Revere singled to load the bases.

Burnett struck out Kratz following a 10-pitch at-bat and fanned Pettibone.

But Rollins took a 2-2 pitch off his leg to force in a run. Burnett then struck out John Mayberry Jr. to end the inning.

Pettibone worked out of trouble in the first after Starling Marte led off with a double and advanced to third on a flyout. Pettibone fell behind Andrew McCutchen 3-0 before striking him out looking at a fastball on the outside corner. Mayberry then saved a run with a fully extended, diving catch on Jones' liner to right.

"That was great," Pettibone said. "Who knows what would've happened after? It was a big play."

Though Manuel wouldn't commit to it, Pettibone's sharp outing almost assures he'll stick around. The Phillies will need a fifth starter for a while.

"He made some good pitches at times," Manuel said. "He got them out when he needed to. He did fine."
